A student is given four different powdered metals and some dilute sulfuric acid. The student wants to investigate the reactivity of the four metals. Outline a method that the student could use to investigate the relative reactivity of the metals. The plan should use the fact that all four metals react exothermically with dilute sulfuric acid. You should name the apparatus used and comment on the safe use of the chemicals.
